1 Amplifiers
The TDF8551J has a complementary quad audio power amplifier that uses BCDMOS technology.
It contains four amplifiers configured in Bridge-Tied Load (BTL) to drive four speakers: two front and two rear channels.
The I2C-bus enables diagnostic information of each amplifier and its speaker to be read separately.
Both front and both rear channel amplifiers can be configured independently in line driver mode with a gain of 20 dB (differential output) or amplifier mode with a gain of 26 dB (BTL output).
